EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 689,222, dated December17, 1 1- Appllcation filed May 31, 1901. Serial No. 62,547. (No modelJgeneral being to obtain an improved machine in which the machine shallpunch the stock or material in which eyelets are to be set and feed andset the eyelets automatically.

Certain features of the invention are designed to be employed inmachines for setting a single eyelet at a time; but in its more completeembodiment the invention comprises a machine in which'a number ofeyelets may be set at one operation. When it is designed to set a singleeyelet at a time, the machine is provided with a singlepunch and acorresponding pair of eyelet-setting members or setting-tools. When itis designed to set a number of eyelets at one operation, a machineembodying the invention is provided with a gang of punching-toolsproperly arranged to punch a number of holes at a single operation inthe material in such position relative to the latteraud to each other asmay be desired and with cooperating gangs of settingtools for settingthe eyelets in the previouslypunched holes. The punching-tools mayadvantageously be arranged to cooperate in the punching operation withone gang of the setting-tools or sets, each of which latter acts as acombined punching and setting anvil, and the said punching tools arearranged in a manner to support and guide the eyelets in the settingoperation. I

Figure 1 of the drawings is an elevation of the front portion of amachine embodying the invention. Fig. 2 is aview thereof, partly insection, on the vertical plane indicated by Fig. 3 is a side view moreespecially designed to illustrate the application to the machine of aform of eyelet-feeding mechanism which may be employed. Figs. 4, 5, and6 are sectional detothe accompanying draw- V tail views designed toillustrate the working of the parts in punching a hole in the materialand setting an eyelet. Fig. 7 shows in front elevation one. of thedetachable blocks or mountings carrying the gang of punches and the gangof setting-tools with which the punches are more immediately associatedin the machine. Fig. 8 shows in end elevation the block of Fig. 7 andthe parts which are carried thereby.

Having reference to the drawings, 1 designates the fixed framework ofthe machine, and 2 is an operating-shaft mounted in suitable bearings 33 at the front of the said fixed framework, the said shaft beingprovided with suitable means of communicating movement of rotationthereto, a simple band-pulley 4 being represented for convenience ofillustration. Any approved and suitable driving arrangements may beemployed in practice.

The punches 5 are tubular'and are in screwthreaded connection with thepunch-carriers 6, the latter being open at one side, as at 61, for theegress of the pieces of material which are punched out. Thepunch-carriers 6 are mounted in chambers in a block 7, having slots'8,with which the openings 61 register, thereby permitting of the escape ofthe'said pieces of material. The punches 5 work in central holes'throughthe upper sets 9, the latter being in screwthreaded connection with theblock 7 and each thereof having the annular setting-shoulder 91 aroundthe hole in which the hollow punch works. The lower sets are shown at10, they having each the annular setting-shoulder 100 and the centralpunching table or surface 101, against which the punch is arranged tocut. The lower sets 10 constitute, combined punching and setting anvils.They are carried by a block 11, which is mounted on the bed 1 of themachine.

At 12 are shown raceways, which maybe of usual character andconstruction, they extending at their lower ends into close proximity tothe punching and setting devices, and at 13 is shown a supply-hopper,which in practice will be provided with means of any approved characterfor delivering eyelets to the raceways 12. The raceways, the means 142on the head of the machine and being pro- 1 of supplying eyeletsthereto, and the means of operating the raceways may in practice be ofany suitable and approved construction. For thepurposes of illustrationI have shown the raceways as attached to the hopper and. the latter inturn as mounted upon horizontal slide-rods 14, only one of which isshown, although in practice a pair thereof will be used-namely, one ateach end of the hopper-the said rods being fitted within guides thestock or material b, resting on the lower sets or anvils 10, the punches5 first are depressed, causing them first to pass through the saideyelets, so as to pick them off the raceways when the latter areretracted, and then causing said punches by acting against the materialb to punch the holes in such material for the reception of the eyelets.The punches remain within the said holes, as in a Fig. 5, and then theupper sets 9 are caused to descend, forcing the eyelets lengthwise alongthe said punches, so as to cause the bodies or barrels of the eyelets toenter the said holes,'and finally clenching or setting the eyeletsagainst the lower sets or anvils 10, as in Fig. 6.

I have shown in the machine embodying the invention the punch-carriers 6as operated by a cam 16 on the shaft 2, the descent thereof beginningprior to that of the upper sets 9. The uppersets are operated by meansof eccentrics 17 on the shaft 2, straps and con necting-rods 18, andpins or bolts 19, engaging at their inner ends the slide or carriage71,"

which last is fitted to move vertically in ways at 20 on the fixedframework of the machine. The block 7 is detachably applied to the slideor carriage 71 ,heing held to the latter bya faceplate 72, which isremovably secured in place onsaid slide or carriage by means of screws731. On removing the face-plate 72 the block 7 is exposed and may beremoved and replaced. This enables a block 7, containing a gang of uppersets and punches spaced apart with relation to one another suitably forperforming one variety of work, to be taken out of the machine andreplaced by a similar block having corresponding sets and punchesdiiferently spaced. The block 11 is similarly removably applied to thebed 1. In the illustrated embodiment of the invention it is placedwithin a vertical hole or opening in the said bed and is supportedvertically by means of laterally-projecting flanges 111 at its upper endresting upon the top surface of the bed-plate. The punches are raisedfrom their depressed positions by means of springs 61, surrounding thepunch-bars 6 between the top of the block 7 and heads or collars 62 onthe said punch-bars. For the purpose of holding the punch-bars fromrotation, which would carry the openings 61 thereof out of register withthe slots 8 in the block 7, the punch-bars are provided withlaterally-projecting pins 63, working in vertical slots 73 in the block7. The punched-out pieces of material after issuing through the slots 8in therefor, the corresponding upper set being retained in use.

I claini as my invention- 1. An eyeleting-machine comprising,essentially, in combination, an eyelet-set provided at the centerthereof witha fixed solid anvil against which the punch acts in cutting,a secondeyelet-set having the central hole therethrough, and the hollowpunch working within the said central hole, rela-- tively movable withrespect to the second eyelet-set and acting against the face of thefixed solidanvil of the set first mentioned, substantially as described.7

2. An eyeleting-machine comprising, essentially, in combination, aneyelet-set provided at the centerthcreof with a fixed solid anvilagainst which the punch acts in cutting, asecond eyelet-set having thecentral hole therethrough, the hollow punch working within the saidcentral hole, relatively mov: I

able with respectto the said second eyelet-set,- and acting against theface of the fixed solid anvil of the set first mentioned, a carrier forsaid punch, and means for separately operating the said carrier and theeyelet set through which the hollow punch passes, snbstantially asdescribed.

3. An eyeleting-machine comprising a movable carriage, means foroperating the same, a carrier detachably applied to the said carriage, agang of sets applied to the said carrier, agang of punches applied tothe carrier in connection with the said sets, and means for actuatingthe said punches independently, substantially as described. a

In testimony whereof I affix my signature in presence of two witnesses.
